If You're Not Paranoid About Your Privacy, You're Crazy (theatlantic.com)
Muad'Dave writes: Here's an interesting article at The Atlantic about the prevalence of surveillance and the recent uptick in 'deja-vu' moments where devices seemingly hear your conversations and then attempt to market to you. From the article: "One night the previous summer, I’d driven to meet a friend at an art gallery in Hollywood, my first visit to a gallery in years. The next morning, in my inbox, several spam e-mails urged me to invest in art. That was an easy one to figure out: I’d typed the name of the gallery into Google Maps. Another simple one to trace was the stream of invitations to drug and alcohol rehab centers that I’d been getting ever since I’d consulted an online calendar of Los Angeles–area Alcoholics Anonymous meetings. Since membership in AA is supposed to be confidential, these emails irked me. Their presumptuous, heart-to-heart tone bugged me too. Was I tired of my misery and hopelessness? Hadn’t I caused my loved ones enough pain? Some of these disconcerting prompts were harder to explain. For example, the appearance on my Facebook page, under the heading “People You May Know,” of a California musician whom I’d bumped into six or seven times at AA meetings in a private home. In accordance with AA custom, he had never told me his last name nor inquired about mine. And as far as I knew, we had just one friend in common, a notably solitary older novelist who avoided computers altogether. I did some research in an online technology forum and learned that by entering my number into his smartphone’s address book (compiling phone lists to use in times of trouble is an AA ritual), the musician had probably triggered the program that placed his full name and photo on my page."
In every example given, initial worst assumptions give way to mundane explanations. What exactly is there to be worried about?
Either way the men with the white coats are coming after you... or maybe the men with the funny glasses with an extra band on one side.
Those who don't learn from history...

Of course the author just told the readership of The Atlantic... and by extension many others.
On a serious note, I wonder what online calendar it was? Anyway, the AA meetings are "secret." Not so much searches.

The basic rules:
1) Do not use "free" services that require you to identify yourself in some way. This includes most any service from Google, Facebook, etc.
2) Do not use "free" apps on your smart phone. It is next to impossible to prevent an app on your smartphone from providing ID information to outside entities.
3) Basically - learn the first rule of life - there is no such thing as a free lunch. If someone is giving you something for free, then they are taking something from you without telling you - in our modern era, that is almost always your identity in some way shape or form.
If you leave your mobile's Wi-Fi enabled whilst your out and about, there are HW/SW packages that gather everything about you and your device they are able to gather such as IMEI, phone number, MAC address to profile you across other properties the owner might possess. They buy and sell lists with this info to identify and analyse you to "be able to better serve you".
About a year ago, I read a bit about an executive that works for a company that gathers the aforementioned telemetry as well as other info. He basically said that the technology to actually almost spot-on identify anyone almost in real time is almost here. He recommends paying cash for things that could come back to haunt you later: the drink, cigarettes, a night at the pub with mates, a habit of large triple-meat pizzas weekly, you get the point. Using your debit or credit card enables them to track you because these companies buy purchasing habits.
Ditto becoming "friends" with firms online. They couldn't give a monkey's toss about whether you like something; they want to follow you on Facebook to see who your mates are, investigate your peccadilloes, whatever. Insurance companies are already involved with this and are penalising folk already for being "risky". If your friends list is a cast of other guys and girls who like the drink, holiday in risky areas, smoke fags or the other stuff, you are being catalogued for a price increase.
I've taken to using cash, never having my mobile's Wi-Fi on when I'm not at home, never paying with a debit card for the drink, fags, triple curries down the pub, you name it.
Google is not in e-mail advertising business. If you got any ads from maps visit, they would be the usual ones in your search results or banners on 3rd party sites (which do not get access to your e-mail or other identity info). Either you shared your e-mail in some other context related to the event, or your browser and/or mobile device are infected by keylogging/location logging malware.
You should get even more paranoid about your privacy!
Ted Kaczynski is that you? I didn't think they let inmates on Slashdot..
"File to fit, pound to insert, paint to match" - Aircraft Maintenance 101
Many of us have been warning about that trend for decades, to be ignored by the vast majority who do not mind a world with not a single shred of privacy. "What do you have to hide?" they ask.
Those of us who don't want to live in that world sadly have little choice. It's increasingly hard to avoid it, try as you might. You can wall yourself off, refuse to use the privacy-invading tech that everyone else favors, but at the cost of being increasingly cut off from mainstream society and even your own friends who no longer use any non-corporatized online communication. "Why use email when there's Facebook? Dude, get with the times! Nobody's on email man!"
People appear to hate the idea of the original internet: open standards with communications that were not monitized or centrally controlled. They much prefer that it be replaced with proprietary services, closed non-interacting protocols, and corporate-censored for-profit services that monitize everything they do. Thereby, the rest of us are forced to watch the internet we knew and loved be dragged in a direction we hate to see. It feels like destroying everything that made it great. In fact, destroying the very things that allowed it to become as world-changing as it did.
And I say that as somebody who was not young when it was arpanet and Vaxen. Rips out my heart to see what's happened to the place since then. Improvement, good. Development without wisdom, not so much.
Just because you are paranoid doesn't mean they aren't out to get you. But in this case, the author kinda is paranoid. He could use a course on web browsers and email.
The next morning, in my inbox, several spam e-mails urged me to invest in art. That was an easy one to figure out: I’d typed the name of the gallery into Google Maps.
It sounds like the author is alleging that Google gave his email address and marketing information to spammers. Is that true? Considering I have a gmail account that receives no spam at all, I think a more believable explanation is that he dropped his business card into a box somewhere, or signed-up on a list. In reality, 100% of my spam comes to the email address I have registered to my domain. My personal email gets nothing because I don't give it out.
Some people receive almost no spam. Other people get a 200:1 ratio of spam to real emails. Having done tech support, I can tell you by talking to someone for 5 minutes how much spam they get. Do they click on ads? Do they sign-up for stuff and give out their email? Do they play the lottery? Then they are in the high spam category. I bet a reporter is one of those people who gives out his contact information to absolutely everyone.
Another simple one to trace was the stream of invitations to drug and alcohol rehab centers that I’d been getting ever since I’d consulted an online calendar of Los Angeles–area Alcoholics Anonymous meetings. Since membership in AA is supposed to be confidential, these emails irked me.
Unless he created a dedicated email address specifically for the AA membership, he has no evidence of this. Again, more likely, he enaged in networking.
I don't even want to consider his example where his bluetooth somethingorother was transcribing his words and turning that into spam. That one is technically possible, but we just aren't there... yet.
With those complaints registered, many of the anecdotes in the story do make sense. A Google search triggered targeted ads on YouTube. Well yeah, Google owns both sites. This is one of the reasons people feared Google Plus: it was just *too* well integrated. I am just surprised that this is news to people at all. What do you think is in that 35 page license you clicked "accept" to in order to play that free Facebook game? Why do you think that flashlight app needs access to your contact list and the internet?
With GPS, facial recognition, voice prints. Everything that the US/UK gov and mil used to have in the 1970's~90's is now at a consumer level. :)
The "number into his smartphone’s address book" is all part of the free social media experience.
The "William Binney, a government whistle-blower and former top NSA cryptologist, the answer was simple: almost everything, today, tomorrow, and for decades to come." should be clear to most readers.
The "Its employees dealt with us in an upbeat, tightly scripted manner that appeared to stem from their awareness of several cameras angled toward the service counter." is just the expanded 'chat down' program that all tourists and travellers now face

if you use closed source software then there is no way of knowing what your handheld computer is actually doing without going to extreme measures.

Anons need not reply. Questions end with a question mark.
Think of it this way: what makes a single "mature" depends on who's looking. For a teen, it's anybody over 20. For a twenty-something, it's somebody in their mid-30s. For a senior citizen, it's somebody around their own age.
Good, inexpensive web hosting
That's like keeping your front door wide-open and putting a sign in your yard that reads 'Steal my shit' then getting mad when you're robbed.
It does not require esoteric knowledge to prevent some of the "coincidences" the article discusses. Block ads, block third-party cookies, refuse unnecessary scripts... those actions will actually prevent some of this from happening and the authour is negligent to not mention them.
Going to visit the NSA data center, in contrast, accomplishes jackshit.

Don't want to have your information collected, don't use Facebook. I mean seriously, what the fuck is wrong with you? Also, don't let Google or anyone else store a permanent cookie on you, don't stay logged in, don't keep a personal account on the search engine you use. For starters. Also don't use a web-based E-Mail service like gmail and encrypt all your E-mails fanatically. At this point the number of people willing to talk to you will be pretty small, which will make it much easier to not show up in social networks.
For bonus points, pull the battery out of your phone when you're not using it.
Even after all that, you probably won't be a freaking ghost, but at least you'll be making the few guys who know about you work for it.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
We have already been far more than chipped by the nano chips in chemtrails. That is what 'morgellons' is. Morgellons has been proven in study, it is not just on patient's skin, those with the fibers coming out of their skin, their bodies are rejecting the fibers. The chemtrail nano chips self assemble in to fiber optics inside of us./p>

Faster! Faster! Faster would be better!
Except maybe people still using Hotmail or Yahoo Mail. I use Gmail exclusively and the only time I see spam is when I check the spam folder for emails accidentally getting put in there.
I clicked on the link, and AdBlock warned me the site uses targeted ads. LOL. Or maybe not LOL.
We could all benefit from a slick-implemented AI "noise" bot.
It runs plausible searches and emails from your Google account: AA meetings, cancer support, communist party meetings, tea party movement meetings, etc.
Done at a reasonable human-speed rate to make it believable to Google.
I don't code, but if someone wants to do this right (open source) I pledge $50 for the kickstarter right now.
What could possibly go wrong?
adamperry@gmail
Huh, it turns out the article is right. Someone typed the word "AdBlock" and suddenly they are spammed with some ad about a "hosts file engine". That is creepy.
You are paranoid about security and have a Facebook account? You bring shame to Paranoid schizophrenics everywhere. Please join your local chapter of technologically illiterate anonymous.
On a more serious note. I know people who are convinced that Navy seals sit in the trees outside their house. You are halfway there. Get help before it is too late.
My first run-in with online privacy happened in the late 1990's when a persistent troll found personal info on me and broadcast it all over discussion boards in an attempt to embarrass me into silence.
I realized after the "breach" it's easy to leave inadvertent clues. Somebody with enough patience and persistence can put these clues together to dig around in search engines for personal info and your online trail.
And there are plenty of freaks out there who make the Interwebs their sadism engine. It's their only "power" in life.
I'm much more careful about "crossing topics" now. For example, if I'm on a board about pets, I don't talk about IT and vice versa. But, that's probably still not enough as one tends have certain phrasing patterns that leave sufficient clues for "statistical linking". Most trolls probably don't go that far or are not smart enough, but you never know. They may have a script-buddy to barter for zombie PC time or something.

No it's not. The sign provides consent.

No seriously though, you should not trust people who are monitoring you without your consent, but you should trust that whoever has been is no longer doing so. :) There there, see I know you could do it. Who's a good employee? *rasberries* hahaha You're a good employee. puts headset down
Just be like everyone else, join a team, join a group of people. Then those who monitor you can know that you are clearly part of that team and monitor you as a part of the whole. Never stand out, just stay under the radar, avoid all attention, and do your job. Nope, nooooo! Nooooo! Stop it! Good. Who are we? We don't exist. There's no one watching you, you're being crazy. Shhhhhhh get back to work. Will you just get back to work?

I guess that's what passes for "off the grid" these days. Not hard.

I have a facebook page too - it's not real but I have one.
Those are a few horrible fads and hardly constitute a regression from civilized society. There was a time when putting your real name on-line would get you laughed off of slashdot. sad.

Whenever I read one of these articles about how tiny fragments of information are gathered and assembled into a personal profile I'm struck by how much is based on so little. They make a lot of assumptions about the veracity of these little details that they collect. Thins makes me wonder if active and deliberated injection of miss information could serve as an effective defense mechanism.
If course, you'd have to be sure that the false picture you paint is a favorable one. And that the resulting ad targeting will come in a fairly innocuous form. You are going to get blasted with ads regardless of what you do.. Do you want them to be relevant (attention getting, so you are constantly telling yourself, "No, no, no") or completely irrelevant to you (more annoying, but soon more easily ignored).
Perhaps a browser plugin could be developed that does occasional random searches in the background. Or maybe something that clicks on random ads in a hidden browser session (just make sure you have damn good sandboxing, given the propensity for drive-by browser exploits to lurk behind ad-bait.) Similar things could be done with random email and text messages between users of a misinfo application. I've often thought it would be fun to make a browser plugin that connects to a peer-to-peer network and swaps tracking cookies with other browsers. You'd have to make sure to exchange only cookies from domains know to be associated with tracking and advertising, and not anything that may have login of other confidential data. This would have to be done carefully; but I think it could be done.
The effects would be hilarious. When you op-out of tracking you merely deny them some of the data (and maybe flag yourself as a different kind of datapoint...). But if you intentionally poison the well in a way that is difficult to distinguish from legitimate data then you increase expenses while significantly decreasing value of the whole system, as well as sow doubt one whatever remains after their attempts to filter out interference.
Limiting your exposure by trying to limit what information can be learned about you will only go so far. You will never eliminate all of it. After you reduce it by 95% there is still a hellofalot that can be gleaned from the remaining 5%. But if that 5% can't be disentangled from 95% bogus information then it would be a real thorn-in-the-side of those trying to build consumer profiles of every member of the population. I think that this is the new frontier in privacy protection. Get a few Cryptonomicon-minded people thinking about this and imagine what they could come up with.
(Posted as AC for obvious reasons.)
allowing google maps to link search data with your account (were you logged in as well?)? giving your phone number to a stranger who uploads his contact data to facebook. using google and probably not even a private browser window for searches. even using facebook in the first place. i'd call that rather naÃve, using all these services without paying money for them and expecting to not give some data back in exchange.
I just updated to Marshmallow, where you can see and control app privileges. I went through the apps and disallowed anything they didn't need. Almost every app had the right to look at my contacts. Music apps, map apps, fitness apps - everything. None of them need this access, but they are all selling it. Hopefully, those days are now over...
Enjoy life! This is not a dress rehearsal.
If you look at the regular Linux desktop, a DNS server is already provided (usually powerdns) in forwarding mode by default in most major distros, so there isn't really any worse efficiency involved in those circumstances when modifying the configuration. Additionally, they're more efficient than hosts files when blocking entire domains, since you don't need to create over a TB of text file to generate every single possible subdomain combintion (which apparently sticks in your RAM according to you) for just one domain.
My DNS daemon running on my router is more efficient. It returns NXDOMAIN for blocked domains, my browser doesn't even attempt to establish a TCP connection to an IP address, unlike when you use hosts files. This protects an entire network of computers and doesn't require any configuration of any individual systems to make it work either. The faster NXDOMAIN responses than resolution means that it is faster than without too.
Blocking an entire domain (or subdomain) is as simple as this line in Bind 9:
zone "abcstats.com" { type master; file "/dev/null"; };
Bind errors loading the zone, because it's not a valid zone file, effecively using next to no memory for a doman now considered invalid.
Change is certain; progress is not obligatory.
Specifically: I use Google and Gmail. I have *never* received spam emails related to searches I've done on Google. And I do a *lot* of Google searches.
Nope. The best orbiting telescopes have a ground resolution in low earth orbit of about 5 cm. That's looking straight down in early morning when the atmosphere is least disturbed. Reading a license plate would require higher resolution and looking through much more atmosphere.

I have three.
There's very little accurate information on any of them.
I was always worried that the feds would tie all their digital resources together and put the smackdown on "us".
I now realize that would ensnare "those that matter" so that will never happen.
Now the private sector has made marketing the winner of that race.

Two things:
1) You're an idiot. Most of what you're talking about is simple tracking cookies based on your browsing habits, you're just not aware of how easy it is to track you across what seems like unrelated sites ... guess what, ITS FACEBOOK YOU FUCKING MORON. What do you think Like buttons ACTUALLY do? They aren't there so you can Like them, they are there so Facebook knows EVERYTHING YOU'VE DONE.
2) Perhaps you should stop using an Android device.
Everything mentioned in the article can be explained by an android device with its shitty permissions stealing information. And it certainly notices when its near other android devices and can easily report that back.
This IS already happening with rogue apps. The question simply becomes, are you using one of those apps?
I say Android specifically because of its all-or-nothing approach to permissions that means people give apps permissions they wouldn't normally because thats the only way they can use the app at all, versus iOS where you simply deny permission to that resource and unless the app 100% depends on THAT resource, you will get rejected from the app store if you don't function without that resource. I.E. No forcing users to allow you to track them in your app that has no reason to track them.

""One night the previous summer, I’d driven to meet a friend at an art gallery in Hollywood, my first visit to a gallery in years. The next morning, in my inbox, several spam e-mails urged me to invest in art. That was an easy one to figure out: I’d typed the name of the gallery into Google Maps."
That does not make a lot of sense. If you started to see ads in Gmail about art then it makes sense. Getting spam does not. Google does not make money on email spam and they would not sell your name to a list. Now if you signed in at the gallery and put down your email address that would make sense.
"“People You May Know,” of a California musician whom I’d bumped into six or seven times at AA meetings in a private home. In accordance with AA custom, he had never told me his last name nor inquired about mine. "
You have your phone number in facebook? Even if you do this again does not make a lot of sense. Apple does no share phonebook data with facebook and Google and Facebook do not share data.
Oh and the rant about AA. Oh well.
Sorry but nothing to see here move along.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
When you deal with another person or a business privacy is not really in play. My only objection to anyone deeply studying me is that all other people are not deeply studied. My feeling is that if all people were studied in depth I might look pretty darned good compared to many others. The real issue is lack of equality in data collection and analysis. Further is is all too easy to fool a data mining effort. One might ask Google Maps to give you directions to the local archdiocese or to every major church in the area. Then you might collect addresses and driving directions to every stock brokerage in your area. Then drop some well known names in your emails such as governors with meetings at specific sites and dates and driving directions. One might also make several inquiries into buying the most expensive Mercedes or top of the line Lincolns. You might want to make inquiries about yachts as well. The likely effect is that someone out there may think you buy lots of expensive items and they may butter you up with some gifts designed as incentives. How about yacking about your scholarship fund which does not really exist. Confuse the living daylights out of data mining.
Fair enough, but answer me this one question. Are you a chatbot that ran into a conspiracy site and went nuts?
That's far too black and white. Nearly nobody wants 100% privacy, and it's entirely possible to use a smartphone while maintaining good control over who gets to learn what about you. At least for Android, where you can avoid Google entirely if you wish, and you can install a firewall to prevent applications from talking to the outside world.
Hell, I still laugh at people who use their real names online.
But one solid thing the internet has taught me: "teen" usually means someone aged 20-30.
I don't see where anybody said developers do have such an obligation.
However, the point about closed source is correct. I support the right of developers to develop according to their own tastes, and I equally engage in my own right to avoid closed source software to the greatest degree that I can.
There really isn't any such thing as privacy at this point, just "not being worth bothering to look up."
Any data store worth worrying about has probably been compromised. It's currently fairly easy to identify and then get information you want about any given individual, and as tech advances it's going to become absolutely trivial. Even moreso, new tech will come along making some data that are currently very difficult to obtain easy and then trivial.
You don't have privacy now, you don't even have anonymity. And you probably don't even have "not being worth looking up" because someone SOMEWHERE is probably curious enough about you to at least google you or something.
The best course of action, IMO, is to embrace that knowledge and figure out ways to minimize the damage that can be done to you if someone does violate what you imagine is your "privacy." There's no good solution to keeping things ACTUALLY private, but there are plenty of good solutions for minimizing damage of important or personal information being freely available.
Since I can't tell them apart, I treat all ACs as the same person.
Why do "free" apps require access to your address book?
You figure it out...
Problem is, other people (like IT sales monkeys) have my contact information in their address books.
And they ignorantly use "free" apps.
Result: I get targeted spam.
A pox on web designers who feel that window.innerWidth == screen.availWidth
What if other people have my info in their phone and THEY granted Facebook access to their contacts? Facebook could then target both of us in an attempt to get us to connect. In that case, my only fault would be that I gave someone my contact info.
I have a FB-specific e-mail address that nobody else knows and I don't use phone apps that demand too much access to my info.
Do they see the irony of publishing an article about protecting privacy only to ask you to disable your ad blocker?
Went to a large, well-known building complex, Place X, in a large metro area Metro Y which sells a specific type of good (vague enough for you?). Previously had never expressed interest in this type of good. Had not sent or received email / text / FB, / Twitter nothing not even Googled it or Mapquested it since I know where to find this large complex as does everyone else who lives in that Metro Y area.
No reason at all I should have generated any digital data around my spontaneous decision to *walk left three blocks and pop into very large Place X in Metro Y*. Not even a phone call just before or during or just after my visit. Just a person walking with their phone.
Next day, WHAM, 10,000 ads all over Google in my inbox in my spam box about this type of good.
They know who you are, where you are, why (they believe) you are there whether it's online, online using a VPN, probably online using Tor or just walking around. I take that as my reality and have for a few years now.
I have repeatedly and seriously considered giving up my tracking device, er I mean phone. Tried to revert to an earlier technology but it was pre e-911 ability and so my carrier cannot connect it to their (or any) system any longer.
I may still pull the trigger on this dump the phone idea.
I want Congress to step in here and do for us what the EU does for their citizens and more. After all, we're the home of the free, right? I don't feel free when I am tracked constantly. I feel surveilled, exploited and I feel my autonomy, privacy and self-determination compromised by strangers whose current and future motives are unknown to me .
Don't forget that no matter how careful you are with your privacy, not using google services, not using facebook, not posting photos, not having an online social media presense, all it takes is someone you know to save your contact info on their phone and sync it with google, now they have your confirmed email, name, number, and address. All it takes is 1 'friend' to upload a photo with you in it to facebook and tag your face with a name/email.... now facebook has you too. And so on....
You can control your own info, but you can't force everyone else you know to do the same.
When I'm 60, I'm retiring to a cabin ala Walden. Fuck this technology.
Irrelevant when you don't use forwarding rules in your DNS server configuration.
Botnets, sure.
What I'm suggesting isn't a rogue DNS server either.
So does the DNS daemon in my household.
My DNS daemon is local on the network which has certain zone files for resolving certain hosts. Therefore it is 'far faster' than remote DNS servers too.
In my own experience in Europe, OpenDNS seems to be often slower at resolving than my own DNS daemons. Likely because according to my traceroute, it goes through four countries before I hit their server.
My blacklisted domains shows:
$ wc -l /etc/bind/blacklist /etc/bind/blacklist
13736
(also, look, I can split things up across multiple files for organisational purposes)
Most of those entries include all the subdomains of a given known malicious domain, so no duplicate entries needed to filter out various subdomains.
To do what I do with my DNS server, it would take up more CPU, RAM, I/O and disk space with a hosts file and the work would have to be duplicated across each system. However, not each system in my household can even do hosts. Such as the game consoles, tablets and mobile phones. So, even if I was doing /just/ what you were doing, it would not be sufficient.
Change is certain; progress is not obligatory.
According to the author, the only real consequences of his relatively careless use of the internet are that he received targeted ads that could have been embarrassing in circumstances that didn't occur and he knows the real name of guy he met in person and exchanged personal phone numbers with... how frightening.
If you worry about such things you are already a bit paranoid. And if you are paranoid about this but not about your privacy, then sure you are crazy. Not because you are not paranoid enough, but because you are inconsistent.
